2.6 Transponder Mode selection
Press MODE (repeatedly) to select from following Modes:
• STBYÆ „Standby“
Transponder does not respond to any interrogation. Squitter and
ADS-B output is not active.
•ACSÆ„Mode A+C+S“
Standard condition; transponder responds to mode A, C and S
interrogations.
•A-SÆ „Mode A+S, no C“
Altitude is not transmitted (neither on C nor on S requests). All
other Mode-S data as well as Mode-A replies are transmitted.
If no 24-bit address (AA) was defined or entered as “000000“ the
transponder works as Mode A-C transponder, in that case the
following Modes are possible apart from Standby:
•AC- Æ „Mode A+C“
Transponder replies only on Mode A and Mode-C interrogations.
•A-- Æ „Mode A“
Transponder replies only on Mode A interrogations.
In STBY (Standby) mode, all transponder transmissions
are disabled completely! Therefore, the transponder is not
visible in this mode to air traffic control or the anti-collision
systems onboard other aircrafts.
Never use the STBY mode in flight
unless you are requested
to do so by air traffic control. Always remember to put the
transponder in active mode prior to take off!
2.7 Squawk-Setting
The active Squawk is displayed in the upper line, while the standby
Squawk is presented at the lower line.
Setting the Standby Squawk:
• Press
► to set the cursor („^“), turn rotary knob to set numbers
of the standby Squawk.
• Press
▼▲ to activate the Standby Squawk (this moves the
current active Squawk into Standby)

3 INSTALLATION
3.1 Notes
The following suggestions should be considered before installing.
The assigned installation company will supply wiring. For diagrams refer
to 3.6 Wiring.
Remote Header and cables shall be installed according to „FAA AC-
143.13-2A Acceptable Methods, Techniques and Practices – Aircraft
Alterations“ and the appropriate manufacturer’s instructions.

3.3 Unpacking and Inspecting of the Equipment
Carefully unpack the equipment and inspect for transport damages. If a
damage claim has to be filed, save the shipping container and all
packing materials as evidence to your claim.
For storage or reshipment the original packaging should be
used.

Operation and Installation
3.4 Mounting
• In cooperation with a maintenance shop, location and kind of the
installation are specified. The maintenance shop can supply all
cables. Suitable sets of cables are available from Funkwerk
Avionics GmbH.
• Select a position away from heat sources. Care for adequate
convection cooling.
• Leave sufficient space for the installation of cables and connectors.
• Avoid sharp bends and wiring close to control cables.
• Leave sufficient lead length for inspection or repair of the wiring of
the connector (containing the memory), so that when the mounting
hardware for the rear connectors is removed, the assembly may be
pulled forward several inches.
• Bend the harness at the rear connectors to inhibit water droplets
(formed due to condensation) from collecting in the connector.
• For mounting details/drawing refer to chapter 3.8.2 Mounting
Advices.

Operation and Installation
3.5 Equipment Connections
3.5.1 Electrical Connections
One 9 pin D-SUB miniature connector includes all electrical connections.
When powering the remote control not by the output of the
switched power output of the remote controlled device but
directly by the aircraft’s power supply, the power input line
(+UB) must be equipped with an external fuse (1Amp./slow).
3.6 Wiring
3.6.1 Conductor Cross Section
Power Supply (Power, GND): AWG20 (0,62 mm²)
Signals: AWG22 (0,38 mm²)
The conductors must be approved for aircraft use. RX and TX should be
shielded individually, or at least be pair-twisted and shielded together.
